SUMMARY

The discussion centers on the controlled addition of sodium dichromate dehydrate in water solution to benzhydrol during oxidation in glacial acetic acid. Adding the reagent dropwise prevents rapid exothermic reactions that could lead to bubbling and loss of control over the reaction kinetics. Glacial acetic acid serves as a solvent that stabilizes the reaction environment, ensuring optimal conditions for the oxidation process. This method enhances safety and improves yield by managing the reaction rate effectively.

PREREQUISITES
  • Understanding of organic oxidation reactions
  • Knowledge of sodium dichromate dehydrate properties
  • Familiarity with glacial acetic acid as a solvent

What is the point of adding the sodium dichromate dehydrate in water solution dropwise to benzhydrol in glacial acetic acid? Why can't we just add it all in at once? Also, what is the purpse of the glacial acetic acid?

In such situations it is usually kinetics/evolving heat/bubbling problem or some combination of all three. You want to have the reaction under control, don't you?
